Hand rubbing nuclear fusion live in the wilderness

Chapter 99 CFA Copper Iron Alloys
Hearing the reminder that the task was completed, Han Yuan stopped for a while, then pretended to be nonchalant and continued to walk towards the kiln, but he couldn't help but put a smile on his face.

Although I don't know how to complete it, it's good to be complete, and the most important thing is to get the task reward.

He is looking forward to what the primary material smelting knowledge and information can bring him.

In the kiln, the last fired item was waiting for him.

A simple crucible made of white clay!
This crucible is much larger than the crucible used in the gold shop, and the cup wall is also very thick, nearly two fingers wide.

The space inside can store about three to four hundred milliliters of liquid, which is enough to smelt some metals in small quantities.

Because of his clumsiness, he didn't take it out with the porcelain before, but now he picks it up alone.

The surface of the crucible was not glazed, but the white clay had been fired to the point of crystallization, somewhat resembling the cool white of bone china.

Although it does not look as beautiful as glazed porcelain, it also has a unique flavor.

Originally, he planned to use this crucible to melt the copper pellets refined a few days ago into copper ingots.

However, the completion of the 'material smelting and exploration mission' made him change his mind.

He wanted to see what kind of metals could be fused with copper and iron in the systematic smelting knowledge information.

Holding the crucible, Han Yuan returned to the wooden house and found the copper nuggets and some unused pig iron fragments.

Staring at the copper nuggets and pig iron fragments, he searched for information about the smelting of these two materials in his mind.

It is known from the previous application knowledge information of biomaterials that the amount of knowledge information transmitted by the system is quite large.

He was also prepared for a lot of information to come out, but the result surprised him a bit.

The information that emerges from this search is not specific, but like a directory.

The number of catalogs does not seem to be many, and you can see the bottom by scrolling down a little bit. There are about ten or so items, and each catalog is a kind of smelting information.

This made Han Yuan a little surprised. Compared with the application information of the same basic biological materials, the amount of information on the smelting of this copper-iron alloy is a bit pitiful.

He still remembers that when he checked the application knowledge information of sisal materials, there were countless information, overwhelming all of them.

Curious, Han Yuan clicked on the first catalog information of copper-iron alloy.

After clicking on it, he knew that his previous thoughts might be wrong.

The amount of copper-iron alloy smelting information is so scarce, simply because his search criteria fixed the scope of the information.

He was searching for copper-iron alloys, so the smelting information in his mind was only the smelting methods of these two materials.

In other words, among the dozen or so pieces of smelting information on the catalogue, only copper and iron are included in the smelting materials.

Just from copper and iron, a dozen different materials can be made according to different smelting methods, and the Korean won can only show that the system is awesome.

He didn't know if there were any alloy materials among the dozen or so materials that humans hadn't developed yet.

But there is a great possibility.

It is well known that although the melting points of copper and iron are not much different, the specificity and ease of solidification of the two are quite different.

This has also led to the fact that even after tens of thousands of years of human development, the research and development progress of copper-iron alloys is still very slow, and it is still very difficult to manufacture valuable copper-iron alloys.

This is because the properties of copper and iron are quite different.

If the iron content is less than 2.5%, it is easy to solid solution and form an alloy, while if the iron content is more than 3%, it does not undergo solid solution, but segregation occurs, but the alloy formed by segregation is difficult to use.

Because of the characteristics of the two metal materials, it is difficult to melt pure copper and iron into a new alloy.

Modern alloys are generally made of copper and iron mixed with other metal materials. It seems that there are very few alloys made of pure copper and iron.

Flipping through the information casually, Won found a copper-iron alloy he had never heard of.

This copper-iron alloy, which is systematically named 'CFA alloy', is simply a fusion of copper and iron.

This material has the same electrical conductivity, thermal conductivity, ductility, and elasticity as copper, and also has the same properties as iron, such as wear resistance, tensile strength, hardness, and magnetism.

It can be said that it almost perfectly possesses the excellent characteristics of the two alloys of copper and iron, but eliminates the mutual shortcomings of the two.

More importantly, the CFA material can modify the ratio of copper and iron. Each different ratio is an alloy with different characteristics.

For example, when copper accounts for 90.00% and iron accounts for [-]%, the smelted CFA alloy has quite high hardness and elongation.

But weaker in ductility and conductivity.

When the proportion of copper in the CFA alloy reaches 90.00%, the smelted CFA alloy has excellent electrical conductivity, ductility, corrosion resistance, etc.

But it is far inferior to iron in terms of hardness.

In the past, in order to obtain materials with various characteristics, human beings used various metals, alloys, resins and other material combinations to obtain some inherent characteristics.

The wide variety of materials is cumbersome both in manufacture and use.

But now, he looks at the 'CFA alloy' which is a single material with multiple properties.

The only disadvantage is that the manufacturing process is more difficult, and he doesn't even think about it given his current conditions.

Roughly flipping through the information about CFA alloys, the Korean Won people are all stupid, their mouths are dry, and they can't help swallowing saliva to relieve it.

From this material alone, he saw the value of smelting knowledge information.

It can be said to be infinite.

The emergence of a new type of alloy often represents a lot of technology that will be promoted.

Especially copper and iron, these two kinds of materials have quite large reserves on the earth, so there is no need to worry about the shortage of raw materials.

If this new type of CFA copper-iron alloy material is released on the earth, it may easily create a new market of tens of billions.

No wonder the protagonists in the novel who got the system are so awesome.

After being absent-minded for a while, Han Yuan realized that he was still broadcasting live.

Although the audience couldn't see the information and the virtual screen in their minds, it gave people a feeling that something was wrong with him being so stunned and not moving for a while.

So a lot of the bullet screens in this meeting are asking him what's wrong.

After recovering, Han Yuan raised the crucible in his hand and said, "Do you still remember the copper that was collected and smelted a few days ago?"

"Because copper has the effect of disinfection and sterilization, I plan to melt the collected copper, first make a copper bucket to hold water, and make the remaining copper into copper ingots for the next live broadcast."

"And what I have in hand is the crucible that I specially fired yesterday, which can be used to melt copper."
